What version of stayopen are you trying to install? Version 3.0.2 from AMO *is* incompatible. There is a compatible version listed in the first post: viewtopic.php?f=48&t=633732You'd need to use 3.1.1a1 for Firefox 56.

Have received the FF 57 update, and changed the about:config key for bookmark menus to stay open on middle click. Thanks so much for getting this into core Firefox.

But there's no way to have stay-open-on-middle-click on History menus in standard Firefox 57, or in the location bar dropdown other than running Nightly with the option to enable legacy extensions - is that correct? (Not so bothered about the History menus, but would really like the stay-open-on-middle-click in the location bar dropdown.)

@DavidGB - yes, you understand correctly. I think there's a webextension called UndoCloseTab or something like that which is being recommended as an alternative to keeping the History Menu open. And the location bar dropdown functionality is wanted in Bug 1364415. I might at some future time attempt to get that one fixed too. Feel free to follow the bug, just don't spam it.

As I said, I'm not really bothered about the history part, just the location bar. Ironically this might push me back towards Chrome, where I use an add-on that provides a newtab page that (among other things) implements the Firefox location bar (mixing results from search, bookmarks, history and open tabs, and using the database setup and sorting algorithm Firefox uses for location bar results) ... and it keeps the dropdown open when selecting with middle-click. And it otherwise replicates layout and functions from the Firefox newtab page which Firefox has lost with the new FF57 newtab - to my considerable regret.

It looks like SOM breaks alt+enter, ctrl+click for post data searches in the urlbar, which I don't think I noticed|reported before. It looks like only the url-s are loaded and the search is not performed. (Both 4.0b1 and 3.1.1a1)Is there any chance for a fix for it?

There's also an issue when you want to step after you searched. For example you alt+enter on "some search term" then you want to move the cursor back to change to "some other search term".in this case the current site url gets loaded back.

(How about the old "pressing escape should give back focus to content" thing)

Thanks for the report. Unfortunately, stayopen is probably not going to get any further updates. In Fx 59 the Options/Preferences button disappears from the Add-on Manager (viewtopic.php?f=23&t=3035377). I thought perhaps bootstrapped add-ons might be safer from this sort of dismantling (Remove support from non-bootstrapped exts), but apparently not. I'll probably concentrate any future effort into getting features into Fx itself. As mentioned in my previous post, the location bar aspect might get into native Fx eventually.

I see. There's still FF56/52ESR/Pale-moon/Basilisk/Waterfox then for the 3.1 line, but I guess you're not interested in updating for these either.

Unless I actually decide to use one of them, probably not. Not really happy about the end of xul, but I've found acceptable (though not quite as good) replacements for much of what I frequently use (and hopefully more to come before end of support for ESR), so current plan is to stay with Fx.

when will browser.bookmarks.openInTabClosesMenu to work with folders? in bookmark button/panel/sidebar/menubar/etc?* middle-clicking/ctrl clicking a bookmark folder* right-clicking the bookmark folder and choosing "Open All in Tabs"* navigating to the submenu and left-clicking "Open All in Tabs"That's what stooping from switching to FF57+Will it make into 59ESR?
